Self Propelled Gun/Rocket Launcher

According to Yankee, reloadable and disposable is a change of way to think about MLRS. Previously it's thought of as a different flavor of artillery. So the launch tubes are the guns and the rockets are ammo. When you need to fire you (re)load the tubes with rockets.

More recently these big 300mm and 370mm rockets are getting developed by people like CASIC, who naturally think of them as simplified missiles. To them it makes much more sense to have the rockets seal inside a capsule coming out of the factory as a single unit. Then the launch vehicles just have to worry about loading a whole module at a time, fire and get rid of the empty module, as you would say a pre-loaded ATGM. Its a different view on who the tube belongs to, the vehicle or the rocket. Being modular has a lot of advantages and is the way of the future, but one disadvantage is if the container is one use it's more wasteful.

So in this case there are a lot of 300mm rockets left over for PHL-03, those are intended to be reloaded into tubes and PLAGF don't want them to go to waste and would like PHL-16 to also be able to use them. Hence 4 cell 300mm rocket modules that allow reloading even though they're technically modular.
What I understand from reading the posts so far.
- 5th tube is loadable but isn't because of reusability concerns related with the existing PHL-03 rocket stock (reloading the module compromises the structural integrity?)
- When the 5th tube is fired, the module should be discarded as determined by the PLA (or manufacturer?).

My understanding is:
- 370mm rockets for both export and PLA use, only has 4 tube modules. There are no 5 tube modules
- 300mm rockets for export come in 5 tube modules, and for PLA use has 4 tube modules. In the export 5 tube module, it is not intended to be equipped for repeated use. In the PLA 4 tube module, the "central tube" is not actually a tube at all but is for structural reinforcement only.

There is no 5 tube 370mm module.

Oh I see, I was thinking the debate about the "functional" 5th tube was for the 370mm rocket module.

But how does the 10 tube "standard loading" mentioned in @Taiban article fit in all this if the 5th 300mm tube has been converted into an unusable structural reinforcement? That is why I was thinking the 5th tube is loadable depending on whether the unit wants to reuse that particular 300mm module

As I understand it, there is no module with 5x 370mm tubes, whether it be functional or not.

I think when he says "standard" he's talking about the export AR3 (which is the export version of the PHL16/191).
As I understand it, the export AR3 has 300mm modules that come in 5x 300mm tube modules that are not particularly reusable.

The domestic PHL16/191 has 300mm modules that come in 4x 300mm tube modules with a central non functional reinforcing tube, but is reusable.

Structurally it doesn't make sense for the 5th tube to be loadable/functional or not dependent on whether they want to reuse it -- because structurally if you want it to act as reinforcement, it would be odd to have the same tube to be able to actually work if you happened to want it to work.

If we look carefully at the domestic PHL16/191 4x 300mm module, we can see that the central "tube" is actually smaller in diameter than the outer four tubes, which lends me to believe that the outer four are the ones which are actually functional, and the central one isn't.
Heck the central tube may not even have the same internal diameter as the other four, meaning it may not even be able to accommodate a 300mm rocket in terms of physical dimensions, even if it wanted to.

I would think it may be useful to think of the "central tube" not as a "tube" but rather as a "reinforcement cylinder" because using the word "tube" would make it seem like it has the option of actually accommodating and launching a rocket.

In other words, the net effect of this hypothesis for the domestic PHL16/191 is:
- 370mm loadout module -- unchanged, still 4x 370mm rockets per module
- 300mm loadout module -- likely reduced from our previous understanding, as 4x 300mm rockets per module with a central reinforcement cylinder (instead of 5x 300mm rockets per module as assumed from the export AR3), however with the caveat that it is designed for more reuse than the AR3 5x 300mm module is.

In that case, is the 370mm loaudout module reusable as well?

Thank you for the clarification though I do hope they add the 5th rocket back for the 300mm module but maybe I place more emphasis on the saturation bombardment capability of an MLRS than the PLAGF command (though I do know the 122mm caliber rockets are more suited for the role).

Perhaps the 4 x 300mm module is only for use whilst there are still 300mm rockets in stock, and the long term aim is to convert completely to 370mm?
